The invention discloses a
nitrogen-doped graphdiyne riveted
transition metal monatomic catalyst as well as a preparation method and application thereof. According to the catalyst,
nitrogen atoms are doped in a novel carbon material graphdiyne carrier,
transition metal single atoms are riveted on the surface of
nitrogen-doped graphdiyne through the covalent effect between the
transition metal single atoms and N and C atoms, and thus transition
metal is uniformly dispersed on the surface of the nitrogen-doped graphdiyne in a single atom form to form the catalyst.
Transition metal atoms in the catalyst are uniformly dispersed on the surface of the nitrogen-graphdiyne-based catalyst in a single atom state, a large number of active sites are provided for oxidation-reduction reaction, graphdiyneis adopted as a
carbon substrate and has excellent morphological characteristics, formation of catalytic active sites is facilitated, and catalytic advantages of single atoms are brought into play. The catalyst disclosed by the invention has high electrocatalytic activity on
oxygen reduction under an alkaline condition, is simple and effective in preparation process, low in cost and easy to popularize and put into production, and has important significance in the field of fuel
cell development and application.
